Oh, come on. ICE’s new detention center, Alligator Alcatraz, is nothing like a concentration camp. For one thing, historians unanimously agree that Nazis never used alligator-infested moats. Maybe things would have been different if they had access to a bunch of crocodiles, but I’m not even sure the European climate would have supported such a project.
Then there’s the barracks themselves. Those are laminated floors in there, and I’m pretty certain Dachau’s were wooden. If they even had floors, mind you. But either way, there’s your answer: different floors entirely.
